Fw 190 - numbers for A-8 and A-9

The limiting factor of R11 production was either the radio or (more likely) the autopilot (I doubt it was the windscreen) and, like the A9 with it's engines, there likely would have been more made if more components were available. And there is no reason at all that the R11 wouldn't have been used on normal daylight missions with other "normal" fighters. All we're talking about (physical difference) is a larger radio and an autopilot. This opinion (and that's all it is, frankly) is based on my research on all-weather 109 numbers and use.
